Yang received a helpful vote for an answer of the question: How do i know if someone has installed profile stalkers on facebook and received 100 points"Even if they do have facebook stalkers "installed", there is nothing to worry about because such trackers don`t actually exist and are just spam.. While in theory a profile tracker could work, I believe that these apps have somehow been prevented from working by Facebook. For example, there used to a app called Trakzor which would tell you who viewed your profile, but it only worked if the other person also had the app installed, meaning they could track you too. It never caught on, and it seems to be long gone. Facebook actually prohibits developers from making apps that can track profile views or estimate the number of visits. So any apps promising the ability to track profile views is in violation of Facebook`s policies and would therefore likely be removed from Facebook as soon as they tried to go live. So, don`t worry, these stalker check apps aren`t legit." 05:56pm May 7, 2013
